Movements used to maintain standing balance in the sagittal plane following a postural perturbation have previously been described as a hip strategy, ankle strategy, or a combination of the two. Numerous extrinsic and intrinsic factors affect which of these postural strategies are typically employed. To our knowledge, no studies have investigated fatigue in this regard. Therefore, the purpose of this study was to investigate the effect of lumbar extensor fatigue on postural recovery strategy in response to a balance perturbation.
